Re: [Gumstix-users] Running programs on startup

Marq, what version of the gumstix filesystem are you running? This seems
to be an older version which I'm not familiar with. However, what you
want to do is pretty simple and the same example would work well in
either this setup or the init I'm more familiar with. Basically, the
start scripts are just sh scripts with a set of predefined functions
(start, stop, restart, some others). So, you take the outline, and fill
in what the start function needs to do. There are lots of examples you
can find for doing init scripts using google. My example based on your
example is below.

The following excerpt should work just fine for starting your app. Fill
in the stop code however you want, but it's not required. Just put it in
/etc/init.d and name it S60StartHeli I guess. In newer versions of init
on the gumstix, the directory /etc/init.d contains the scripts without
numbers, and then there are symlinks to the scripts in the rcX.d
directories.
# S60StartHeli init file
PATH=/sbin:/bin:/usr/bin:/myfiles
case "$1" in
start)
i2c-load --reset 0x0b write i2c-io.hex
sleep 1
/myfiles/IMU_control
;;
stop)
;;
restart)
stop
start
;;
*)
echo "Usage: StartHeli {start|stop|restart}"
exit 1
esac
exit 0
